As Japan’s workforce ages, they look to replace retiring workers with robots.  As the population pyramid in the US flattens out, will we have to do something similar?  It seems likely that as countries move from a developing status to “developed” nations, their populations will also flatten out.  As a comparison to the US, check out Japan’s population pyramid.  They are simply farther along a curve that technology is likely to take countries.  Combine this with the advances of technology worldwide in general.  Consider Licklider’s paper from 1960, or Vannevar Bush’s seminal article from 1948 to see both two amazing prognosticator’s, and how far technology has come in that time.
